What IRS Form 1120-L (2018) Is For

IRS Form 1120-L (2018) is the federal income tax return designed explicitly for life insurance companies operating within the United States or foreign corporations engaged in similar insurance business activities. It reports taxable income, deductions, and investment income to determine the company’s income tax liability under the Internal Revenue Code. This form ensures that each life insurance company accurately documents its annual financial results, including capital gains, losses, and retained earnings, for proper tax assessment.

In addition to standard income reporting, Form 1120-L requires companies to disclose detailed financial statements and balance sheets that align with National Association of Insurance Commissioners (NAIC) standards. These records help verify reserves, policyholder obligations, and total assets reported for the tax year. Both domestic and foreign corporations must use this form to maintain compliance, ensure transparency, and meet federal income tax return requirements for insurance companies.

Common Mistakes and How to Avoid Them

Many life insurance companies make similar errors when filing IRS Form 1120-L (2018), which can lead to penalties or processing delays.

• Using the Wrong Tax Rate: Some filers still apply the pre-2018 corporate rate of 35% instead of the 21% rate. Always verify the correct rate before computing your company’s income tax liability.
  
  
• Omitting the NAIC Annual Statement: Companies often forget to include the National Association of Insurance Commissioners (NAIC) annual statement. Always attach or retain the complete statement to support reported totals.
  
  
• Miscalculating Reserves: Errors in calculating life insurance reserves under Section 807 rules are common. Review reserve computations carefully using updated 2018 tax reform guidelines.
  
  
• Mailing to the Wrong Address: Sending the return to an incorrect IRS service center can cause significant delays. Confirm the current mailing address for Ogden, Utah, before submission.
  
  
• Skipping Schedule M Reconciliation: Some corporations fail to include Schedule M when not required to file Schedule M-3. Always attach a complete schedule to reconcile the gross and taxable income properly.
  
  
• Misunderstanding E-filing Rules: Many filers assume electronic submissions include all attachments. Annual statements must be retained separately and made available upon IRS request.

What Happens After You File IRS Form 1120-L (2018)

Once you file IRS Form 1120-L (2018), the IRS reviews and processes your corporate income tax return to verify accuracy and completeness. Processing typically takes several weeks, but late or amended filings may take longer. You may receive notices requesting clarification or additional supporting statements related to reported income, deductions, or investment activity. Maintaining copies of your tax return, balance sheets, and annual statements ensures faster resolution if the IRS requires verification.

If additional tax is owed, interest and penalties accrue from the original due date until payment is made in full. Refund claims for overpaid income tax are processed within standard timeframes as long as they were filed before the three-year refund statute expired. Companies that disagree with adjustments can appeal IRS findings by providing supporting financial statements and documentation.
